Ancient fern savannahs may have transformed parts of Europe into a wildfire-prone inferno during the end-Triassic mass extinction. New fossil evidence suggests the ferns repeatedly regrew after fires, creating fresh fuel that helped prolong the ...
Colorectal cancer is now the leading cause of cancer death among people under 50, and cases in younger adults continue to rise. Warning signs can include persistent bowel changes, recurring rectal bleeding, dark or narrow stools, unexplained weight ...
Miniature brain models grown from patients’ cells revealed striking differences in how Alzheimer’s-related tissue responds to an antidepressant. The organoids and the particles they release could eventually guide more personalized treatments and ...
Researchers discovered a proton-assisted mechanism that greatly improves how triplet energy moves between quantum dots and nearby molecules. The proton briefly shifts position, helps coordinate electron movement, and then returns to where it ...
MIT engineers have found a way to give chip-based lidar a wider, clearer view without relying on moving parts. Their design uses differently shaped antennas that can sit close together without scrambling one another’s signals. In tests, the system ...
Scientists have found a way to revive vancomycin, a powerful antibiotic that some dangerous bacteria have learned to resist. Instead of creating an entirely new drug, researchers paired vancomycin with a small molecule called pghi-4, which blocks a ...
Researchers are applying evolutionary theory to cancer by changing treatments before tumors have time to develop resistance. Mathematical models suggest that rapid, carefully timed switches between multiple therapies could improve cure ...
A single dose of psilocybin produced measurable changes in brain activity and possible changes in brain structure that lasted for up to a month. Participants who experienced the greatest increase in flexible, varied brain activity also reported more ...
Scientists have created a programmable optical chip that can slow light on demand, giving engineers far greater control over how optical signals propagate through a circuit. The technology could provide the delays, synchronization, and buffering ...
For most adults, a daily caffeine habit may be safer for the heart than many people assume. A new American Heart Association review found that up to 400 milligrams of caffeine a day, roughly three to five cups of regular black coffee, is generally ...
Watching television very often in midlife may be linked to troubling brain changes decades later. In a study of about 1,700 adults, frequent TV viewers later showed smaller brain regions involved in memory, decision-making, and visual processing, ...
Ancient sediment reveals that some of K’gari’s deepest lakes vanished around 7,500 years ago, despite unusually heavy rainfall. The surprising discovery suggests changing winds and future climate ...

Scientists are testing two promising ways to destroy PFAS, the stubborn “forever chemicals” that can accumulate in water and resist normal treatment. One method uses collapsing vapor bubbles to ...

The asteroid that wiped out the dinosaurs was likely an exceptionally rare CO chondrite from a distant region of the solar system. Its unusual chemistry suggests that planet-cooling dust and debris, ...

Researchers have uncovered a surprising culprit behind sleep loss in Alzheimer’s disease: the brain’s own immune cells. In mice with amyloid plaques, overactive microglia triggered inflammation ...

A catastrophic asteroid breakup may have triggered a huge wave of impacts across the inner solar system about 800 million years ago. The debris was launched from near a gravitational gateway ...

JWST has captured unusually detailed images of gas feeding the supermassive black hole at the center of NGC 4696. A vast filament appears to funnel material into an 800-light-year-wide spinning disk, ...

An ancient sea worm may hold the secret to a whole new category of natural materials. Its jaws combine proteins and metal ions in a way that gives them metal-like strength and unusual mechanical ...

An unusual leopard gecko that naturally develops aggressive tumors may become an important new model for cancer research. Scientists found its tumors share key genetic changes with human cancers, ...

A deadly fungus has wiped out amphibian populations around the globe, yet some mysteriously recover. Researchers discovered that survivors develop powerful immune defenses while they are still ...

A team of mathematicians used whimsical "silly sprinklers" to solve a physics mystery that has puzzled scientists for decades. Their experiments showed that the rotation of both normal and ...

A new review highlights exciting progress in atomically thin quantum materials where light and magnetism work together in ways never before possible. In these materials, light-generated excitons can ...

Four nearby white dwarf stars have been discovered hiding in plain sight beside brighter red dwarf companions. Hubble's ultraviolet observations finally revealed the long-hidden stellar ...

Why do beaches today have seashells from clams and snails instead of brachiopods? A new study suggests the answer lies in Earth's greatest mass extinction, when warming oceans and falling oxygen ...

Researchers have recreated the physics of extracting energy from a spinning black hole using a stationary device that produces synthetic ultrafast rotation. The achievement transforms a long-standing ...

A drug originally developed for spinal cord injury may offer a fresh approach to treating Alzheimer’s disease. In mouse studies, KCL-286 repaired dangerous DNA damage, reduced inflammation, and ...

A newly developed material can control and "program" heat, allowing it to direct thermal radiation, switch modes, and remember its settings without continuous power. The innovation could ...

Astronomers have uncovered 31 of the oldest known quasars, including the two earliest ever detected, shining from a time when the universe was only about 670 million years old. Powered by ...

Water’s odd behavior becomes even more dramatic when it is supercooled, but scientists have struggled to compare the many different ways of describing its microscopic structure. Researchers at the ...

NASA's Hubble Space Telescope has captured a spectacular red, white, and blue view of one of the Milky Way's oldest star clusters to celebrate the nation's 250th anniversary. Hidden ...

Hubble has captured a spectacular view of LH 95, where about 2,500 young stars are still on their journey to becoming full-fledged stars. Scientists discovered these growing stars can keep pulling in ...

Celebrating the United States' 250th anniversary, NASA released a stunning Hubble portrait of Messier 3, an ancient globular cluster with more than 500,000 stars. The remarkable cluster is ...
